14' x 10' x .04167' (1/2") = 5.83 cu. ft of volume
5.83 x 7.48 gallons/cu. feet = 43.63 gallons per 4.7 seconds.
Divide by 4.7 seconds = 9.28 gallons/sec.
9.28 x 60 x 60 x 24 = 801,792 gallons/day
That is my math on the page Dean. Hopefully, that way if I did a term wrong someone can correct my error.
Good luck on your pond management. That sounds like a very healthy water flow rate to keep what you want IN your pond, and let what you don't want OUT of your pond fairly quickly.
